You have to be pretty tough to be an actor, and you have to be pretty certain what you want. You can't waffle through this business.

When you're younger you have a lot of ideas and you're probably more insecure, all those things. I work with young actors now and I see their insecurities and I make fun of them. I don't make fun of them but I make them laugh, because I know what they're going through. When you get older you think 'It's only a movie after all, it's not brain surgery.'

The movie industry is full of crazy people who think that they are god.

Whether it's overeating or it's overworking or over-sex or whatever it is, alcoholism, drug addition, we push ourselves to the brink and then pull back because it's kind of exciting.

I think the first British actor who really worked well in cinema was Albert Finney. He was a back-street Marlon Brando. He brought a great wittiness and power to the screen. The best actor we've had.

I've got a great sense of humor.

I worked with Lawrence Olivier some years ago. He was a great mentor.
